Abstract

This invention discloses a multi-layer superpositioned brushless motor structure including stators with multi-sheet circular brackets and rotors of multi-sheet hoop round brackets arrayed in lamination alternately coaxial to the stator, wind-wire window axes circular-arrayed in equal distance on each stator are parallel along the motor shaft and the poles of a magnet on each rotor arrayed in equal distance in circulation are parallel along the motor shaft, the polarities of magnets arrayed adjacently on a same stator are opposite and the polarity direction of magnets aligned along the stator plane normal are the same on different stators. As a generator, the rotor rotates to form a rotation magnetic field, and a stator winding is induced to generate electromotive force and mechanical energy is turned to electric energy, as an engine, time sequence current drives the stator winding to generate rotation magnetic field to drive the rotor rotating, so electric energy is turned to mechanical energy. Advantage: the staggered layer number of the stator and rotor brackets can be added and deleted according to the power requirement of a motor.

Description

A kind of multilayer laminated brushless motor
[technical field]
The present invention relates to a kind of electrode, be specifically related to a kind of high efficiency multilayer laminated brushless motor.
[background technology]
Traditional no brush electrode adopts the multiple working procedure non-oriented silicon steel sheets that the multi-disc punching press is good such as punching press, cleaning, riveting moulding to be pressed into iron core, and the coiling enamelled wire is made into motor stator thereon again.The silicon steel material that this scheme is used is many, Heavy Weight, and punching press and spooling equipment costliness, processing link is many, and cost is high.Because use iron core, iron loss is inevitable, the motor gross efficiency is difficult to carry De Genggao.Because magnetic circuit communicates in the wired bag of institute, so be difficult to realize high-efficiency and low-cost distributed digital chemical control system at the independent lines bag.Again because the silicon steel sheet punch forming process makes the motor stator and rotor that must make large-size with the anxious liter that brushes of the cost that reaches the technical scheme that obtains bigger moment under same line bag drive current.Also, cause the resistance of start big owing to huge attraction between iron core and the permanent magnet.The motor of this structure generally only is used as common generator, is difficult to make the generator of peak efficiency and least cost.If, need high performance semiconductor power device and embedded intelligence chemical control system system as high-performance motor, and the cost height, it is big to promote resistance.
[summary of the invention]
The technical problem to be solved in the present invention provides the design of a kind of electric machine structure, can realize in light weight, cost is low, power expansion is easy to motor, can realize that again the high pulling torque slow-speed of revolution simplifies the motor of gearbox.No matter be generator or motor, all have the characteristic of high-efficiency and low-cost, particularly motor, the consumption reduction that can greatly economize on electricity, economy and social effect are great.
For addressing the above problem, the technical scheme that the present invention takes is: a kind of high efficiency multilayer laminated brushless motor, comprise that J annular support arranged on it, and J 〉=1, each support equal intervals has been installed the stator of M line bag, M 〉=2; Comprise that also K rim formula garden shape support arranged on it, K 〉=1, each support equal intervals has been installed the rotor of N permanent magnet, N 〉=2; The annular support of a slice stator is by the rim formula garden shape support of a slice rotor, and alternately stack is by the continuous motor that is assembled into of central shaft.Be installed in the line bag on the stator annular support, its axis direction is parallel with the normal direction on its support plane, place, is that the angle with this direction is not more than 60 ° at least.When J 〉=2, radians such as the line bag on the same support are arranged, and the line bag on the different support is along this place's plane normal direction alignment.Be installed in the permanent magnet on the rotor field spider, its magnetic field axis direction is parallel with the plane normal direction of place support, is that the angle with this direction is not more than 60 ° at least.When K 〉=2, the radians such as permanent magnet on the same support are arranged, and the adjacent permanent polarity of the magnetic field is staggered, and the permanent magnet on the different support is along this place's plane normal direction alignment, and polar orientation is identical.
Stator support and rotor field spider are replaced the overlapping electrode that assembles, can be used as efficient power generator; Be equipped with suitable driver, can be used as high-efficiency electric motor.When being used as generator, apply mechanical force and drive rotor generation rotating magnetic field, in stator line bag, produce electromotive force, expeditiously mechanical energy is converted into electric energy.When as motor, drive circuit applies the sequential electric current in stator line bag, and the combination results rotating magnetic field drives the rotor rotation, expeditiously electric energy is converted into mechanical energy.The electrode that uses this technical scheme to make, efficient height, cost are low, have a extensive future, and market potential is huge, has fabulous economic and social benefit.
